ICE-SAW.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 29, 1907. Serial No. 354,704.

To all whom it may concern:

Be it known that I, JOHN BAYLEss, of Wellsburg, Brooke county, West Virginia, have invented a new and useful Improvement in Ice-Saws, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a side elevation of my improved saw; and Fig. 2 is a longitudinal cross-section of the blade on line II-II of Fig. l.

. My invention relates to the class oi ice-saws, and is designed to provide a device oi this character, by means of which the ice cake need only be sawed lor a short depth, and can then be split apart easily and with little loss of ice. i

To that end the invention consists in combining with the saw a blade or blades which may be driven into the groove cut by the saw to split open the block.

It further consists in means for `striking the blade, and also in the construction and arrangement oi' the parts as hereinafter more fully described and claimed.

In the drawings, I show an ice saw in which the saw blade is made in three sections 2, 3 and 4, these sections being secured in a backing 5 carrying the handle 6. These sections are spaced apart, and in the spaces between the sections are arranged the knives or vertically moving blades 7. These blades are in alinementiwith the saw sections, and are preferably guided thereon by thin plates 8 which are riveted to each side of the knives and project over the saw sections to guide the knives in their vertical movements. The upper parts of these knives are also guided within the backing, and their upwardly projecting stem portions 9 are arranged to be struck by a hammer 10 secured to a lever ll pivoted to the handle at l2. The reciprocating blades are preferably normally elevated by a leaf spring 13 secured to the backing and engaging lugs or recesses 14 on the knife stems.

In the use of the device, the saw is used in the ordinary manner to saw into the ice block a certain distance, and the hammer is then elevated and dropped or swung down forcibly to strike both oi the knife stems. The

blades are thus driven downwardly to split open the block. A projection l5 may be used on the hammer for elevating it by the thumb.

The advantages of my invention result from the combining of the reciprocating blade with the saw. By the use of these blades which are driven downwardly under the blow of the hammer, the block may be cleaved in twain with little or no loss of waste ice, and with the use oi only a shallow saw groove.

Many changes may be made in the orm and arrangement oi the saw, the blades, and means or driving them downwardly, etc., without departing from my invention.

I claim:-

l. An ice saw having a reciprocating blade mounted thereon; said blade being arranged to move toward and from the working edge of the saw; substantially as described.

2. An ice saw having a reciprocating blade mounted thereon, said blade being in the plane of the saw and ar ranged to move toward and from the saw edge; substantially as described.

3. An ice saw having a blade formed in separated sections, and a reciprocating blade between the sections; substantially as described.

el. An ice saw having a reciprocating blade mounted thereon, and a hammer device attached to the saw for striking the blade; substantially as described.

5. An ice saw having a blade with a stern projectingupwardly above the saw back, said blade being in the plane of the saw and arranged to be moved toward and from the edge of the saw blade; substantially as described.

G. An ice saw having a reciprocatory blade, a spring arranged to normally hold the blade elevated, and a ham mer device attached to the saw for striking the blade to depress it; substantially as described.

T. An ice saw having a reciprocatory blade substantially in the plane of the saw, and guides extending transversely of the saw to guide the vertical movement of the blade; substantially as described.

S. An ice saw having its saw blade formed in separated sections with a vertical reciprocating blade between them, and a hammer attachment pivoted to the saw and arranged to drive the blade downwardly, said blade being guided in the saw back; substantially as described.

ln testimony whereof, l have hereunto set my hand.

JOHN BAYLESS.
